Until the advent of the data tool, most clients could follow this simple recipe
to integrate their data with the Discovery Search Engine. New clients should integrate
their data with the data tool. For more information on the data tool, refer
to Data Tool.

Support for the builtin changeset publisher will be limited in future releases.
It should be considered a deprecated feature.

Create de-normalized views of your searchable entities

Write or re-use a changeset publisher on top of those views.

Configure the Discovery Search Engine to pull data from that changeset publisher
as a feed.

De-normalized views should be created for each searchable entity with
the following constraints.

Each view needs an id column (string or numeric) and a last modified
column (date/time).

The ids should be unique across all the views. If you have multiple views
then the ids should have a suffix appended to them to make them unique.

If any columns contain multiple values they should be converted to a
delimited string (e.g. “green,orange,blue” or “green orange blue”).
An additional view is required to track deletes, this need only contain
the id and last modified columns.

The views are a great integration point as it allows you to directly see
the data that is available to the engine.

Or you can go to the Admin tab in the web interface and enter the feed
information there. Note that feed settings in discovery.properties are
read once and then stored persistently in the discovery.settings file.
Any further changes should be made via the Admin tab in the web interface.
